BCY-X offers the best in terms of speed, stability and durability imo. 452 is an incredibly stable material but is surpassed in all around performance by X. Donít take my word for it, call Brad @ 60x and talk to him but Iíve been using it exclusively since it came out with zero complaints.

Why we can have the discussion here. If you are running 452 on open cables like an Elite, Bear etc.... the material simply wonít take the abuse. Served cables through a roller guard are a better fit, with the X itís a non-issue with either. The SK90 on the X is a revamped dyneema vs the 75 in the 452 and will fuzz less all things being equal. The added Vectran in the 452 could possibly be a little more stable but if the threads are built properly its a wash. Personally I think the X is slightly softer on the shot and is a little quicker for what itís worth. For a bowhunting rig thatís exposed to the elements the X is hard to beat in terms of durability and gives up absolutely nothing in terms of down range performance. Not hating on the 452, Iíve had great success running it on my cables with an 8190 string but at the end of the day I can roll with the X and call it good.

It's tough to beat bcy x for a compound bowstrings. It's the best speed, durability and stability all wrapped into one.

It's hard to argue with a guy who builds strings for a living.

I have been using 452X for years and years, never a complaint, build 'em right and they are perfect for their entire lifespan. It does get a little fuzzy over time, but not a concern for me. I pretty much build new strings once a year for my bows and a few for friends here and there.
